It is a protein fragment derived from the carboxyl-terminus of the transferrin receptor, a membrane-bound protein that plays a crucial role in the transport of iron ions across the placenta and other cells. Hephaestin is also involved in the regulation of iron metabolism and is implicated in disorders such as hereditary hemochromatosis.
